Because she was killed in very similar circumstances to the other practitioners who are being targeted and murdered, it's assumed that she's another practitioner. But no one in the Ordo Lebes recalls ever meeting Jessica. That makes her the odd corpse out.[2]

Harry and Murphy go to the Velvet Room, now called Executive Priority Health, to investigate. They talk to Ms. Demeter. Jessica lived near Helen and would ofter travel back and forth to work together. That is probably when Madrigal Raith saw them together and assumed that Jessica was another practitioner and killed her in the House Raith style.[4]
